Think you will find the monarch 767 has electrically assisted l1 and l2 doors, you may not realise where the switch is as it on the attendants panel and looks like 2 light switches with small arrows. Not sure about the zoom aircraft although the neos aircraft which are sister ships to the second 2 nc and na have electric doors.
The 757-300 has a tail skid and vacuum lavs, and the cargo doors are very different on the 767 ( the fwd lifts and drops into the hole, the aft is similar to the 757 )
On the 767 the turn off lights are in the wing root, the 757 are on the nose gear.
On the 767 you have access to the ee bay through the cabin.
The 767 has less flaps and a bulk cargo door on the lh side of the aircraft.
The best thing about the 767 rev's are an option of electrical opening, have worked on pw40000 with this and have heard that there is an option on the ge also.
